When this worked, briefly, it was great. Easy to set up and worked just fine. Simple.

Then, after reworking the site a bit for a customer, it did not work. The tab I am supposed to get to control the magnifier never showed up in my WooThemes Sliding theme. No response from support and I have noticed one or two others seem to have the same problem.

The versions of WooCommerce and Sliding did not change and I think there was a update for the Zwoom plugin to fix a few bugs, nothing major.

It worked once and not now. Why?

Major disappointment, because when it worked, they deserved a donation for their fine work.
